This invention relates to a CAR T cell that secretes CTLA-4 nanobody targeting FAP, its preparation method, and its application. The CAR T cell is a T cell modified with chimeric antigen receptor FAP VHH-HIStag-CD8-CD137-CD3ζ-CTLA-4VHH-GFP, the nucleotide sequence of which is shown in SEQ ID NO.1. The preparation method of the CAR T cell includes: constructing a recombinant lentiviral vector, packaging lentivirus, infecting T cells with lentivirus, inducing in vitro, expanding and culturing, and obtaining engineered CAR T cells that secrete CTLA-4 nanobody targeting FAP. FAP-CTLA-4 / Nb CAR T cells have a good killing effect on FAP-positive tumor cells. The killing effect of FAP-CTLA-4 / Nb CAR T cells on tumor cells is related to the expression level of FAP in tumor-associated cells, providing a new strategy for adoptive immunotherapy of tumors.

The utility model discloses an energy -conserving communication computer lab, including room body and setting heat dissipation structure at room body top. Heat dissipation structure includes installation frame, heat dissipation board and drive structure, and heat dissipation board is equipped with first ventilation groove, and is driven rotation through motor and speed reducer, and the angle is dynamically adjusted to high -efficiently discharge hot air in room body. Multiple heat dissipation structures are evenly arranged in room body top, and central is equipped with air extraction device, and contains mounting plate, installation platform and exhaust fan. The upper end surface of installation platform is inclined plane, and the mounting plate is equipped with second ventilation groove and third ventilation groove, and the hot air discharge path is optimized. The cover is established to exhaust fan outlet end, and prevents foreign matter from entering. Room body top lays solar cell panel, and supplies power for exhaust fan and drive structure, and reduces energy consumption. The present application realizes efficient heat dissipation, energy -conserving environmental protection and high reliability through intelligent adjustment heat dissipation board angle, optimization air current layout and green power supply, is applicable to various scale communication computer lab, has remarkable economic benefits and popularization value.
